Glossary

  • Refraction index: for a transparent medium, ratio between the light speed in the air and the light speed in the medium ; for a reflective surface in the air or vacuum, the refraction index is « - 1 »
  • Brewster angle: particular angle of incidence of a light wave on a refracting surface annihilating? the reflection for the TM polarization
  • TE polarization: polarization of a wave whose electric field is perpendicular to a considered plane ; in the case of a wave incident on a surface, the considered plane is the incidence plane ( containing the wave direction and the normal to the surface )
  • TM polarization: wave whose magnetic field is perpendicular to a considered plane ; in the case of a wave incident on a surface, the considered plane is the incidence plane ( containing the wave direction and the normal to the surface )
